Description

  The present invention relates to a gaming machine equipped with a decoration device using light from a light source.

2. Description of the Related Art Conventionally, in a gaming machine such as a spinning cylinder game machine or a ball game machine, a decoration device using a light source is provided in order to appeal the presence of the player to the player. In particular, in a gaming facility, in the vicinity of the place where the spinning machine is installed, the room lighting is darkened so that the player can easily see the pattern of the rotating light-emitting drum, for example, in a normal room of a gaming facility. Dimming is performed so that the illuminance is about ½ of the illuminance of the illumination.
In addition, a gaming machine may be provided with one or a plurality of acoustic speakers in order to output a sound effect with a sense of presence that is used to produce a gaming machine. Such an acoustic speaker is provided in front of the design surface of the outer frame of the gaming machine, particularly above the design surface so that the player can easily hear the sound effect. For this reason, the acoustic speaker is often arranged at a position that is easy for a player to visually recognize.

  Therefore, a gaming machine has been proposed in which a part of the acoustic speaker provided in the gaming machine or the periphery of the acoustic speaker is illuminated with a light source such as a light emitting diode (LED) so as to easily attract the player's interest. (For example, see Patent Documents 1 and 2).

  For example, in the speaker device disclosed in Patent Document 1, an illumination unit having a decorative LED is provided in a case unit attached to the front side of the speaker body, and visible light output from the LED is a center cap of the speaker or Reflected by the cone, it is emitted toward the player.

  Further, the speaker unit disclosed in Patent Document 2 includes a vibration body that generates a sound wave, and a frame that includes a vibration circuit and a mounting portion for a magnetic circuit section that includes the vibration body and vibrates the vibration body. In the frame, the periphery and the vibration body located outside the vibration body are formed of a light-transmitting resin, and light from the light emitting means located behind the frame is transmitted through the frame periphery and the vibration body. Composed.

  Furthermore, as a decoration device that uses a light source together with a speaker, for example, an annular light guide is disposed around a speaker provided in a radio cassette player or the like, and light from a light source such as an LED is incident on the light guide. A light emitting device has been proposed in which light is emitted from the light guide toward the sound output direction of the speaker (see Patent Document 3).

JP 2003-117082 A JP 2009-118467 A JP-A-9-212107

  In the technique disclosed in Patent Document 1, since the LED for illuminating the cone is arranged so as to protrude in front of the cone on the front surface of the speaker body, a part of the sound emitted from the cone of the speaker body is obtained. As a result, the quality of the sound reflected from the LED and emitted from the speaker is degraded. Moreover, since the light emitted from the LED has a relatively high directivity, uneven illumination of the cone or center cap occurs, and as a result, there is a possibility that a high decorative effect cannot be obtained.

  In the technique disclosed in Patent Document 2, since the light source is arranged behind the speaker, the light from the light source is blocked by the member of the speaker body, and the entire cone cannot be illuminated uniformly. In addition, when processing for irregularly reflecting light is performed on the peripheral edge of the frame or the like, the proportion of light transmitted from the light source toward the front surface of the speaker decreases. For this reason, in order to enhance the decoration effect, the number of light sources is increased or a high-luminance light source is used, so that the power consumption of the light sources increases.

  Furthermore, in the technique disclosed in Patent Document 3, although light can be emitted from the entire light guide so as not to have uneven brightness, the speaker itself is not illuminated, so that the speaker emits light when viewed from the player. Therefore, there is a possibility that a high decorative effect cannot be obtained.

  Accordingly, an object of the present invention is to provide a gaming machine including a decoration device capable of enhancing the decoration effect by illuminating a member facing the player side, such as a vibrating body of a speaker, evenly. .

And an optical member. The light guide member has at least one incident surface facing each of the at least one light source and an end surface facing the diffusion member of the light guide member, and guides light from the light source incident through the incident surface. The light from the light source is emitted toward the diffuse reflection surface from a wide range of the end surface facing the diffusion member rather than the incident surface.

  In this decorative device, it is preferable that the diffusing member is a diaphragm of a speaker, and the diffuse reflection surface is a surface on the side of the diaphragm that emits sound.

A third reflecting surface provided on the outer periphery of the light guide member and the first and second reflective surfaces, and totally reflecting the light reflected by the first reflective surface or the second reflective surface toward the end surface of the light guide member; It is preferable to have a reflective surface.

  Furthermore, in this decoration device, the light guide member further has an emission surface provided on the front side of the light guide member, and the end surface of the light guide member facing the diffusion member reaches the end surface from within the light guide member. The closer to the front surface of the light guide member, the more light is refracted and emitted toward the diffuse reflection surface, and the other portion of the light reaching the end surface is reflected and emitted from the emission surface. It is preferable that the light guide member is formed in a tapered shape so that the inner diameter of the light guide member is reduced.

  The decorative device further includes a cover disposed on the front surface of the diffuse reflection surface, and the cover is formed of a light transmissive member, and a plurality of the diffuse reflection surfaces can be directly visually recognized from the front side of the cover. It is preferable that a hole is provided and light diffusely reflected by the diffuse reflection surface is further diffused in at least a part of the periphery of the plurality of holes.

  Furthermore, it is preferable that at least one light source of the decoration device includes a plurality of light emitting elements having different emission colors. In this case, the gaming machine includes a control circuit that changes the color of light emitted from at least one light source by turning on at least one of the plurality of light emitting elements according to a gaming state in the gaming machine. Furthermore, it is preferable to have.

  The gaming machine according to the present invention has an effect that the decoration effect can be enhanced by causing a member facing the player side such as a vibrating body of a speaker to shine evenly.

  FIG. 1 is a schematic perspective view of a ball game machine equipped with a decoration device according to an embodiment of the present invention, as seen from the player side. FIG. 2 is a schematic rear view of the ball game machine 1 shown in FIG. The ball game machine 1 is arranged on the outer periphery of the game board 2 provided in the most area from the upper part to the center part, the ball receiving part 3 and the operation part 4 provided in the lower part, It has an outer frame 5 that constitutes a gaming machine main body together with the game board 2, a decoration device 6, a control circuit 7, and a power supply circuit 8. Further, the ball game machine 1 has a ball payout device (not shown) that temporarily stores game balls and pays out a predetermined number of game balls to the ball receiver 3 in accordance with a control signal from the control circuit 7. .

  The decoration device 6 according to one embodiment of the present invention is attached to each of the upper left corner and the upper right corner of the outer frame 5 on the front side of the game board 2. As will be described later, the decoration device 6 has a speaker and a light source, outputs a sound according to the game situation according to a signal from the control circuit 7, and blinks the light or emits light. Or it is comprised so that the interest of a player may be heightened by changing a light quantity.

Next, the decoration device 6 will be described in detail.
FIG. 3 is an exploded perspective view of the decoration device 6 with the speaker body attached to the outer frame 5. In order to simplify the drawing so that it can be easily seen, the decorative device on the right side as viewed from the player is omitted except for the cover. 4A is an exploded perspective view of the decoration device 6 without the cover as viewed from the front, and FIG. 4B is an exploded perspective view of the decoration device 6 without the cover as viewed from the rear. . Further, FIG. 5A is a schematic side view of the decoration device 6 excluding the cover, and FIG. 5B is a surface that passes through the center of the decoration device 6 and is orthogonal to the front surface of the ball game machine 1. It is a schematic sectional drawing of the decoration apparatus 6 in.
As shown in FIGS. 3, 4 (a), (b) and FIGS. 5 (a), (b), the decoration device 6 includes a speaker body 11, a plurality of light sources 12, a light guide member 13, A substrate 14 and a cover 15 are provided.

  The speaker body 11 outputs a sound corresponding to the sound signal received from the control circuit 7. For this purpose, the speaker body 11 includes a diaphragm 11a that generates air vibrations and a magnetic circuit (not shown) that vibrates the diaphragm 11a in accordance with the waveform of the audio signal. In the present embodiment, the diaphragm 11a is an example of a diffusing member. The diaphragm 11a is formed in a cone shape from an opaque material such as paper, resin, or metal. And the diaphragm 11a is arrange | positioned so that it may become concave shape seeing from the player side. The shape of the diaphragm 11a is not limited to the cone type. The diaphragm 11a may be formed in a polygonal pyramid shape, for example, and may have a flat plate shape or a dome shape. Further, the front surface of the diaphragm 11a, that is, the surface that emits sound waves on the side facing the player is roughened, for example, so as to be a diffuse reflection surface that diffuses and reflects light from the light source 12.

  Each of the plurality of light sources 12 emits one or more light emitting elements that emit light having directivity and a driving circuit. In this embodiment, each light source 12 has red LED, green LED, and blue LED as a light emitting element. Each light source 12 turns off all light-emitting elements or turns on at least one light-emitting element in accordance with a control signal from the control circuit 7. Further, the control circuit 7 may adjust the amount of light emitted from the light emitting element of each light source 12 by, for example, pulse width modulation. In addition, each light source 12 may have white LED as a light emitting element, or may have any one of red LED, green LED, or blue LED. The plurality of light sources 12 may each include a light emitting element that emits light of a different color.

As shown in FIG. 4B, the plurality of light sources 12 (six in this embodiment) are arranged on the back surface of the substrate 14 provided on the front surface of the speaker body 11 at substantially equal intervals along the outer periphery of the speaker body 11. Attached to the side. The back surface of the substrate 14 is a surface facing the back surface of the game board 2 without facing the player in a state where the decoration device 6 is attached to the ball game machine 1. Each light source 12 is disposed toward a central axis that passes through the center of the diaphragm 11 a and is orthogonal to the front surface of the game board 2 so that the light emitting surface 12 a faces the incident surface 13 a of the light guide member 13.
Note that the number of light sources included in the decoration device 6 is not limited to six and may be one or more. However, the number of light sources is equal to or more than the minimum number that the diaphragm 11a is illuminated evenly when all the light sources are turned on when the light sources are arranged at substantially equal intervals along the outer periphery of the speaker body 11. It is preferable.

The light guide member 13 spreads the light from the light source 12, illuminates the diaphragm 11a of the speaker body 11 with a part of the spread light, and directly transmits the other part of the spread light to the player side. The light is emitted. Therefore, the light guide member 13 has a shape substantially equal to the shape of the outer periphery of the diaphragm 11a, and in this embodiment, has a substantially ring shape. The inner diameter of the light guide member 13 is substantially equal to the outer diameter of the diaphragm 11a. The light guide member 13 is disposed between the substrate 14 and the speaker main body 11, that is, in front of the diaphragm 11a so that the central axis of the diaphragm 11a and the central axis of the light guide member 13 are substantially coaxial. The By arranging the light guide member 13 in this way, the light guide member 13 does not have a portion protruding from the front surface of the diaphragm 11a. Therefore, since the sound wave emitted from the diaphragm 11a toward the front surface is not blocked by the light guide member 13, the quality of the sound emitted from the diaphragm 11a is prevented from being deteriorated.
The light guide member 13 is created by molding a resin that is transparent to visible light, such as polymethyl methacrylate (PMMA) or polycarbonate (PC). Alternatively, the light guide member 13 may be created by polishing or molding glass.

6A is a schematic rear view of the light guide member 13, FIG. 6B is an enlarged view of a region B in FIG. 6A, and FIG. 6C is FIG. It is a schematic sectional drawing of the light guide member 13 in line AA 'of FIG.
In the light guide member 13, two light reflecting surfaces are opposed to the light source 12 through the incident surface 13a so that the light from the light source 12 spreads in the light guide member 13 to both sides of the incident surface 13a and propagates. 13b1 and 13b2 (first reflection surface and second reflection surface) are formed. For example, the reflecting surfaces 13b1 and 13b2 pass through the center of the incident surface 13a so that the reflecting surfaces 13b1 and 13b2 approach the end surface on the inner peripheral side of the light guide member 13 as the distance from the vertex located on the normal line of the incident surface 13a increases. That is, it is arranged so as to be symmetric with respect to the normal line of the incident surface 13a across the apex so as to be convex when viewed from the incident surface 13a. The reflective surfaces 13b1 and 13b2 are formed, for example, by providing a slit-shaped air gap in the reflective surface portion of the light guide member 13. In this case, the angle formed between the reflective surfaces 13b1 and 13b2 and the normal line of the incident surface 13a is adjusted so that at least part of the light from the light source 12 is totally reflected by the reflective surfaces 13b1 and 13b2. Alternatively, the reflection surfaces 13 b 1 and 13 b 2 may be formed by embedding a metal film in the light guide member 13.

The positions and shapes of the reflecting surfaces 13b1 and 13b2 are such that the directivity of the light emitting element of the light source 12, the size and refractive index of the light guide member 13, so that the light from the light source 12 spreads substantially evenly on both sides of the incident surface 13a. Based on the positional relationship between the reflecting surfaces 13b1 and 13b2 and the light source 12, for example, it is determined by performing ray tracing and evaluating the spread of light. For example, the reflecting surfaces 13b1 and 13b2 may be plane mirrors, or may be concave mirrors or convex mirrors. Further, the two reflecting surfaces may be aspherical surfaces. Further, the incident surface 13a may be a flat surface, or may be formed in a convex or concave spherical or aspherical surface with respect to the light emitting surface 12a. Furthermore, the incident surface 13a and the reflecting surfaces 13b1 and 13b2 may have different curvatures in the direction along the central axis of the light guide member 13 and in the circumferential direction.
The reflecting surfaces 13b1 and 13b2 may have different amounts of light reflected to the left side of the incident surface 13a and light amounts reflected to the right side of the incident surface 13a. In this case, the shapes and sizes of the reflecting surfaces 13b1 and 13b2 may be different from each other.

  The light reflected by the reflecting surfaces 13b1 and 13b2 travels to the right and left sides of the incident surface 13a on the outer periphery of the light guide member 13, respectively. Therefore, the light reflecting member 13 has a sawtooth reflection surface 13c (third) along the circumferential direction of the light guide member 13 so that the light is totally reflected and directed toward the inner periphery of the light guide member 13. Is formed. In the present embodiment, three reflecting surfaces 13c are formed on both sides of the incident surface 13a so as to be line symmetric with respect to the normal passing through the center of the incident surface 13a. The size of each reflecting surface 13c and the angle formed by each reflecting surface 13c and the normal line of the incident surface 13a are set so that light from the light source 12 spreads substantially uniformly over the entire inner periphery of the light guide member 13, for example, ray tracing. To evaluate the spread of light. Therefore, the angle formed between each reflecting surface 13c and the normal line of the incident surface 13a and the size of each reflecting surface 13c may be different for each reflecting surface. Each reflective surface 13c may be formed in a concave shape or a convex shape.

Further, the end surface 13d on the inner peripheral side of the light guide member 13 is formed so as to face the diaphragm 11a. In the present embodiment, the end face 13d facing the diaphragm 11a means that the end face 13d is arranged so that at least a part of the diaphragm 11a can be directly seen from the end face 13d. A part of the light reflected from the outer periphery of the light guide member 13 is refracted by the inner end face 13d and directed to the diaphragm 11a of the speaker body 11, and the other part is reflected by the end face 13d to be guided by the light guide member 13. The end surface 13d is formed in a taper shape such that the inner diameter on the back surface side is larger than the inner diameter on the front surface side so as to go toward the emission surface 13f of the ring-shaped protrusion 13e protruding toward the front surface side along the inner periphery.
The angle formed by the inner peripheral end surface 13d and the back surface of the light guide member 13 is optimized according to the refractive index of the light guide member 13, the shape of the diaphragm 11a, and the positional relationship between the light guide member 13 and the diaphragm 11a. Is done.
Further, the light from the light source 12 is divided and reflected by the two reflecting surfaces 13b1 and 13b2 having different directions, and is reflected at least twice in the light guide member 13, so that the optical path length becomes long. The light is emitted from a wider range of the end face 13d and travels toward the diaphragm 11a. Therefore, the diaphragm 11 a is illuminated over a wider range than that directly illuminated by the light source 12.

Furthermore, the exit surface 13f, which is the end surface on the front surface side of the protruding portion 13e of the light guide member 13, is reflected by the end surface 13d, and is subjected to a rough surface treatment so as to diffuse the light exiting from the light guide member 13 through the exit surface 13f. It is preferred that Note that a diffusion sheet or the like corresponding to the design of characters, figures, and the like may be attached to the exit surface 13f.
For example, a metal thin film is deposited on the front side of the light guide member 13 so that the light from the light source 12 is not emitted directly toward the player and most of the light illuminates the diaphragm 11a. Then, the light reaching the front surface of the light guide member 13 may be reflected to the back surface side.

  FIG. 7A is a ray tracing diagram for one light source when a part of the light guide member 13 is viewed from the back side, and FIG. 7B is a light guide shown in FIG. It is the ray tracing figure which looked at a part of member 13 from the side. 7A and 7B, each of the plurality of lines 701 represents one light beam. As shown in FIGS. 7A and 7B, the light emitted from the light source 12 propagates in the light guide member 13 through the incident surface 13a. Most of the light is reflected by the reflecting surface 13b1 or the reflecting surface 13b2, and further reflected by the reflecting surface 13c, and then travels toward the inner peripheral end of the light guide member 13. Part of the light reflected by the reflecting surface 13c is refracted by the end face 13d and travels toward the diaphragm 11a, and the other part of the light is reflected by the end face 13d and exits from the protrusion 13e. Thus, it can be seen that the light from the light source 12 spreads almost evenly on both sides of the light source 12, and the diaphragm 11a is illuminated without unevenness.

The substrate 14 is provided on the front side of the speaker body 11 and the light guide member 13. Each light source 12 is fixed to the back side of the substrate 14, and the speaker body 11 is also fixed by screws or the like. Further, the substrate 14 is formed with a substantially circular hole having an inner diameter substantially equal to the outer diameter of the protrusion 13e on the front surface of the light guide member 13, and the protrusion of the light guide member 13 is fitted into the hole. Thus, the light guide member 13 is fixed.
Furthermore, a screw hole for attaching the decoration device 6 to the outer frame 5 of the ball game machine 1 may be formed in the substrate 14.

  The cover 15 is provided on the front side of the substrate 14 and is attached to the outer frame 5. As shown in FIG. 3, the cover 15 has a protection portion 15 a located on the front surface of the speaker main body 11 with the decoration device 6 attached to the outer frame 5. A plurality of mesh-shaped holes 15b are formed in the protective portion 15a, and the player is prevented from touching the speaker main body 11, and the player is provided with the diaphragm of the speaker main body 11 through the plurality of holes 15b. 11a and the light guide member 13 are visible. Therefore, the player can see the light diffusely reflected by the diaphragm 11a and the light emitted from the light guide member 13. In addition, the protection part 15a may be formed in a slit shape, or may be formed in a two-dimensional lattice shape.

The cover 15 is made of an opaque resin or metal. However, the protection part 15a may be formed of a transparent resin such as PMMA or PC. Thus, since the protection part 15a is formed of a transparent member, the player can visually recognize the entire diaphragm 11a illuminated by the light source 12 and the entire front surface 13f of the protruding part 13e from which the light is emitted. Can be more interesting. Furthermore, at least a part of the front surface side or the back surface side of the protection portion 15a may be roughened so as to diffuse light in at least a part of the periphery of the plurality of holes formed in the protection portion 15a. Alternatively, a plurality of particles such as a polymer or metal having a refractive index different from the refractive index of the protective portion 15a for diffusing light may be included in the protective portion 15a.
In this way, since the protection unit 15a further diffuses the light, the player can feel a three-dimensional feeling by the combination of the light diffused from the protection unit 15a and the light diffused and reflected by the diaphragm 11a. The interest of the player can be further enhanced.

  As shown in FIG. 2, the power supply circuit 8 that supplies power to each part of the control circuit 7 and the ball game machine 1 is attached to the back of the game board 2. The control circuit 7 controls each part of the ball game machine 1. For this purpose, the control circuit 7 displays a main control circuit 71 for controlling a ball payout device (not shown) and the like on the display device 23 and an audio for the speaker main body 11 of the decoration device 6. It includes an effect control circuit 72 that outputs a signal and a light source control circuit 73 that controls each light source 12 of the decoration device 6.

The effect control circuit 72 includes, for example, a nonvolatile semiconductor memory and an arithmetic circuit, and determines whether or not to turn on each light source 12 according to the effect program stored in the semiconductor memory and the state of the game. . When each light source 12 includes a plurality of light emitting elements having different emission colors, the effect control circuit 72 may determine whether to turn on each light emitting element. Further, the effect control circuit 72 determines the light quantity of each light emitting element to be lit. For example, the effect control circuit 72 may shorten the blinking cycle of each light source 12 or increase the amount of emitted light as the sound volume emitted from a speaker, which is determined according to the effect program and the game state, is increased. Alternatively, the effect control circuit 72 turns on the light emitting elements that emit the specific color of each point light source 12 in order clockwise or counterclockwise for a certain period so that the light emission of the specific color appears to rotate. May be. In this case, for example, the effect control circuit 72 may control each point light source 12 so that the rotation speed of light emission of a specific color increases as the volume emitted from the speaker increases.
The effect control circuit 72 is connected to the light source control circuit 73 and outputs to the light source control circuit 73 a light source control signal that indicates whether each light emitting element of each light source 12 is turned on or off, and the amount of light when the light is turned on. To do.

  The light source control circuit 73 is connected to a drive circuit included in each light source 12 and turns on a light emitting element included in the light source 12 with a predetermined light amount to each light source 12 according to the light source control signal, for example, by a pulse width modulation method. A drive signal to be turned off is output. As the light source control circuit 73, for example, any of various known control circuits that control the light emitting elements can be used, and thus a detailed description of the light source control circuit 73 is omitted.

  As described above, the decoration device included in this gaming machine can illuminate the diaphragm of the speaker body uniformly using a plurality of light sources such as LEDs that consume less power. Therefore, this gaming machine can obtain a high decorative effect. Further, in the decoration device of this gaming machine, the light source and the light guide member are arranged around the diaphragm and do not protrude from the front of the diaphragm, so that the sound output from the speaker body is transmitted by the light source and the light guide member. Distortion can be suppressed.

In addition, this invention is not limited to said embodiment. For example, each light source may be arranged along the outer periphery of the speaker body on the back side of the game board from the diaphragm and light guide member of the speaker body.
FIG. 8 is a schematic cross-sectional view of a light guide member according to this modification. The light guide member 33 according to this modification has the same shape as the light guide member 13 according to the above-described embodiment except for the shape of the outer periphery near the entrance surface 33a. In this modification, the light source 12 is disposed such that the light emitting surface 12a faces the front surface of the game board. The incident surface 33a of the light guide member 33 is directed to the back side of the game board so as to face the light emitting surface 12a of the light source 12. The front end 33b of the light guide member facing the incident surface 33a of the light guide member 33 totally reflects the light from the light source 12 incident through the incident surface 33a, and the light is guided to the light guide member. It is formed in a tapered shape so as to go to the inner peripheral side of 33.

  Furthermore, according to another embodiment, the light guide member may be formed of a plurality of members. For example, the decoration device may have one light guide member that is formed symmetrically about the normal line of the incident surface facing the light emitting surface of each light source for each light source. In this case, each light guide member has, for example, a shape in which one light guide member shown in FIG. 6A is cut by a line connecting the center between adjacent light sources and the center of the light guide member. A plurality of light sources are arranged at substantially equal intervals along the outer periphery of the diaphragm, and light guide members corresponding to the respective light sources are also arranged so as to surround the outer periphery of the diaphragm.

  According to another embodiment, the diffuse reflection member illuminated by the light emitted from the light guide member may not be a speaker diaphragm. For example, the diffuse reflection member may be a part of the outer frame of the game board. Also in this case, the diffuse reflection member may have a cone shape, a polygonal pyramid shape, or a hemispherical shape that is concave or convex toward the player side. The surface of the diffuse reflection member is roughened so as to diffusely reflect light. Further, the cover may be omitted.
